RESERVOIR FOR HOLDING AND SUPPLYING VOLATILE OlL TO BURNERS.

SPECIFICATION forming part of Letters Patent No. 244,225, dated July 12, 1881.

' Application filed June 17, 1881. (No model.)

To all whom it may concern:

Be it known that I, HERMAN FRITZ, a citizen of the United States, residing at Cleveland, in the county of Guyahoga and State of Ohio, have invented new and useful Improvements in Reservoirs for Holding and Supplying Volatile Oil to Burners, of which the following is a specification.

This invention relates to certain improvements in reservoirs or supply-vessels for that class of stoves or lamps in which the volatile hydrocarbons-such as naphtha, gasoline, and the like-are to be burned directly for the production of heat or light, or to be converted into vapor to be burned for such purposes. In the use of such hydrocarbons accidents are liable to happen, owing to the volatility of the material employed and the liability of the formation of combustible vapors, which are apt to escape from the reservoir or supply-vessel, and, where the light is contiguous to the same, establish a communication between the light and reservoir, which will result in an explosion in most cases, as the reservoir, upon being emptied, takes in a proper equivalent of atmospheric air. Such accidents almost invariably occur in filling the reservoir or vessel while the burners are lighted, the entering liquid in such cases forcing out the collected vapor in the reservoir, which, by its specific gravity, falls to the burners below, and, becomingignited, communicates the flame to the interior of the reservoir or vessel and explodes the contents.

The object of my invention is to obviate the danger above mentioned by so constructing the reservoir or supply-vessel that when it is required to fill it it will necessitate its removal from the pipes leading to the burners, while such removal will automatically close the eduction-passage of the liquid and open the filling-aperture at the top simultaneously, and vice versa, when the reservoir or vessel is secured in place.

My invention consists, first, in combining with the reservoir or supply-chamber of a vapor stove or lamp a valve-casing and a valve having an angular prolongation extending through the bottom of the reservoir, the depending lugs, and the couplin ghaving inclined or cam flanges adapted to be secured to the valve by the lugs, whereby the valves will be automatically opened in the act of applying the reservoir to the coupling and closed when detaching therefrom, as hereinafter set forth; second, in combining with the reservoir, its valvecasin g and valve, having an angular prolongation, the depending lugs and coupling, the vertical rod and cover, the latter being adapted to open and close a filling-aperture at the top of the reservoir, as hereinafter set forth third, in combining with the reservoir, its valve-casing and valve, having anaugular prolongation, the depending lugs and coupling, the vertical rod and cover, the latter being adapted to open and close a filling-aperture at the top of the reservoir simultaneously with the closing and opening of the valve below, as hereinafter set forth; fourth, in combining with the reservoir the valve having an angular prolongation extending beyond the valvecasing, the rod for operating the valve, and the detachable coupling having an angular socket, and a concavity or recess to form a drip-cup, as hereinafter set forth; fifth, in combining with the reservoir the chamber arranged on the top thereof, to serve as a funnel for filling the reservoir and an inclosure for the plate that covers the filling-tube and the opening through which the valve-rod passes, said chamber being provided with a cover having an opening through which the rod of the float passes. These objects I attain by the apparatus illustrated in the accompanying drawings, in which- Figure 1 represents a vertical sectional view of my invention. Fig. 2 is a top view. Fig. 3 is a view of the coupling and flange detached from the reservoir. Fig. 4 is a top view of the coupling by which the reservoir or vessel is connected to the tube leading to the burner or burners. Fig. 5 is a side elevation of the valve and valve-casing and rod for operating the valve, a portion of the rod being shown as broken oil; and Fig. 6 is a perspective view of the coupling which connects the reservoir with the supply-pipe.

The letter A indicates the reservoir or supply-vessel, which may be constructed of metal or other suitable material, of cylindrical or any other desired shape.

B indicates a valve-casin g, which is made in the form of a hollow conic frustum, with a flange, O, which may be secured to the edges of the central opening at the bottom of the reservoir or vessel by any suitable means that will form a liquid-tight joint. The said flange is provided with downwardly-extendin g shoulderedlugsD,the shoulders ofwhich are adapted to engage the inclined or cam flanges E on the coupling F, which is connected to the tube Gr, leading to the burner or burners.

The letter H indicates a valve, which in the present instance is in the form of aconic frustum, and is adapted to fit and turn within the valve-casing B. The valve projects through the bottom of the vessel and an opening in the flange O, and terminates in an angular extension, to, which may be a portion integral with the valve, or may be a nut rigidly fixed thereon by a suitable key-fastenin g. This extension or prolongation of the valve has its seat in a seat or socket, 1), formed in the coupling,with a suitable packing, c, interposed between the end of the said extension at and seat or socket b, in order to form a close joint and prevent the escape of oil or gas. The coupling is further provided with a concavity or recess, d, in order to form a drip-cup that is to collect and retain any oil that may escape from the interior of the reservoir while detaching it for the purpose of charging. The said valve is also provided with a vertical passage, H, and a transverse passage,I, the latter being so constructed and arranged that it can be brought into connection with a transverse passage, K, through the wall of the valve-casing. It is preferable that the opening in the valve be longer than the opening in the valve-casing, so as to insure a full coincidence between the two openings without special observance of the operator. The said valve has connected to it a vertical rod, L, which extends upward through the top of the reservoir or vessel A, and is rigidly secured to a suitable plate or semicircular cover, M, which in the present example is seated on the top of the reservoir, and is adapted to partially rotate thereon, being limited in its movement by a suitable stop or stops. The said cover M is located within a cylindrical chamber, N, at the top of the reservoir A, and is so arranged as to cover the opening through which the rod L passes and cover and uncover an aperture, P, in the top of the reservoir as it is moved by the vertical rod, as more fully hereinafter specified. The aperture P is provided with downwardly-turned edges, which form a seat for a float-valve, R, which is located in a perforated or slotted cylinder, S, extending downward from the top of the vesselAto near the bottom. The said cylinder communicates with the reservoir through the perforations or slots, and thus forms a passage for the introduction of the liquid with which the reservoir is to be charged, being adapted to receive the liquid from the chamber N, through which the apparatus is filled, the said chamber being provided with a removable cap, T, for the purpose. The valve It is provided with a valve stem, U, which passes the vessel and through the removable cover of the reservoir in such manner as to guide the valve in its movement and close it against the downwardly-turned edge at the aperture 1?, and thus close the reservoir or vessel when filled.

The operation of my invention is as follows: In its normal condition, or when filled, the reservoir or casing will be in position as indicated in Fig. 1, with the horizontal passage in the valve in conjunction with the transverse passage in the valve-casin g, which will permit the liquid to flow freely to the burner- While in this position the inclined flanges, bearing against the depending lugs on the flange of the valve-casing, will keep the coupling securely in its seat and form a liquid-tight joint. While the communication is thus established below, the cover will close the filling-aperture at the top. When it is desired to recharge the reservoir after becoming empty, in order to open the filling-aperture it will be necessary to turn such reservoir until the cover has passed away from such aperture. This closes the valve below and releases the reservoir from the coupling, necessitating its removal from the vicinity of the burners during the op-- eration of charging, and thus obviating all tendency to accidents; and to enable the reservoir to maintainitself in an upright position when detached and removed from the supply tube or pipe, it is provided with suitable supports or legs.

In this application I do not claim the combination of a reservoir and a nozzle or part containing the oil-supplying orifice having a socket provided at its top with a drip-cup, said nozzle extending below the reservoir, as the same forms the subject-matter of an application for patent filed by me January 15, 1881.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In combination with the reservoir or supply-chamber of a vapor stove or lamp, a valvecasing and a valve having an angular prolongation extending through the bottom of the reservoir, the depending lugs, and the coupling having inclined cam-flanges and adapted to be secured to the valve by the lugs, whereby the valve will be automatically opened in the act of applying the reservoir and closed when detaching therefrom, substantially as and for the purpose specified.

2. In combination with the reservoir, its valve-casing and valve having an angular prolongation, the depending lugs and coupling, the vertical rod and cover, the latter being adapted to open and close a fillingaperture at the top of the reservoir, substantially as described.
